Patent number: 5055636Abstract: A method and apparatus for sealing a splice enclosure to protect cable splice connections retained therein. The sealing member is a single piece body integrally formed of a suitable material which resists detrimental environmental effects and is resiliently compressible in an axial direction to seal the splice enclosure. Axial compression of the sealing member is employed to create sealing forces both about the outer periphery of the sealing member and between the sealing member and cables projecting therethrough. Reentry into the enclosure does not require destruction of the sealing member and does not require tapes, adhesives or other materials and is hence very time, labor and material efficient.Type: GrantFiled: May 31, 1990Date of Patent: October 8, 1991Assignee: Reliance Comm/Tec CorporationInventor: Donald F.

Patent number: 4976796Abstract: An electrical conductor or cable splice is formed by passing the conductor ends from which any insulation has been removed through a ceramic insert so that portions of the conductor ends protrude out of the ceramic insert. These protruding portions are then mechanically and electrically connected to each other, by example, by soldering, welding, or brazing.

The opposite ends of the sleeve have jaws (5, 6, 7, 8) for radial clamping and axial retention of the two cable ends (1a, 1b) and means are provided for forming a fluid-tight seal between the two half-shells (3, 4) and between the cable and the jaws. The half-shell (4) comprises two end elements (9, 10) which are intended to be fitted over the clamping jaws (5, 6, 7, 8) and a central element (11) which is placed between the two end elements and covers their adjacent edges (9a, 10a).Type: GrantFiled: May 12, 1986Date of Patent: December 8, 1987Assignee: Etablissements Morel - Ateliers Electromecaniques de FavieresInventors: Jacques Morel, Didier Morel

Patent number: 4704499Abstract: A boot, or adapter, for an aerial cable or terminal housing is made from hard material in two halves. The two halves are fastened, or hinged, at one longitudinal edge by a eye-hook-like device and at the other longitudinal edge by a snap lock device. An end surface has a plurality of concentric plates which may be snapped out to allow a cable to pass through the boot. The space between the boot and the cable is filled with a compliant, synthetic material.Type: GrantFiled: June 18, 1986Date of Patent: November 3, 1987Assignee: American Telephone and Telegraph Company AT&T Bell LaboratoriesInventor: Carl W. Faust

Patent number: 4704500Abstract: A rigid but flexible bondbar interconnects first and second electrical cable ends in a vicinity of a splice region thereof, the bondbar being shaped and constructed such that it is substantially rigid when exposed to axial tensile loads below a first value and is irreversibly bent when subjected to axial tensile loads above the first value, an overall flex length of the bondbar being such that both of the cable ends are prevented from being pulled out of the cable repair region.Type: GrantFiled: November 12, 1985Date of Patent: November 3, 1987Assignee: Raychem CorporationInventors: Gerald L. Shimirak, Lowell I. Koht

Patent number: 4701574Abstract: A cable end seal and a closure which includes the cable end seal provides a barrier for a junction against water, the junction being in a cable. First and second end seals are disposed adjacent opposite sides of the junction and palced in compression around the cable, the end seals having an outer convoluted surface which mate with a variable length convoluted tubing bridging member so as to form an environmental closure for the junction.Type: GrantFiled: May 2, 1985Date of Patent: October 20, 1987Assignee: Raychem Corp.Inventors: Gerlad L. Shimirak, Thomas Hunter, Martha F. Story, W. G. Halstead, Paul S. Chan, Christopher J. Swinmurn

Patent number: 4692565Abstract: A closure which consists of a closure body having two segmented end seals. Each of these segmented end seals consists of a support structure and at least two pie-shaped end sections. The end sections are sized and configured for mating with the support structure. Each of the end sections has a portion of its periphery which comprises a segment of the periphery of the assembled segmented end seal so that when the end sections and the support structure are mated together the assembled segmented end seal has a uniform periphery. At least one of the pie-shaped end sections contains an aperture for receiving a cable wherein the aperture is located entirely within the periphery of the section.Type: GrantFiled: February 6, 1986Date of Patent: September 8, 1987Assignee: Raychem CorporationInventors: Lowell Koht, Gerald L. Shimirak

Patent number: 4685764Abstract: A splice organizer for optical cable splices within a splice closure assembly having end walls, supporting bars joining the end walls and bridging between the space therebetween, corresponding optical conductors of optical communications cables projecting into the splice closure space, optical connector bodies terminated to corresponding optical conductors, and optical splices formed by pairs of the optical connector bodies in axial alignment, to transmit optical signals between corresponding optical conductors terminated to the optical connector bodies in axial alignment, a series of receptacles for the corresponding pairs of optical conductors. Each of the individual splice organizers cooperates with an adjacent splice organizer, and the last one with an end plate, to provide an individual receptacle for holding therein the optical splice and loosely coiled lengths of corresponding optical conductors.Type: GrantFiled: April 30, 1985Date of Patent: August 11, 1987Assignee: AMP IncorporatedInventors: John C. Hoffer, Bernard G. Caron, Martin R. Rupert

Patent number: 4684764Abstract: A two piece, plastic, bayonet locking housing for assembly over a high voltage cable splice to protect the splice and exposed concentric neutral wires. End seals are provided at the cable entrances to the housing to prevent the entrance of dirt and moisture and take the form of closely conforming rubber tubes. The rolled tubes are mounted on the slotted cable entrance ends of the housings and held there by the hoop forces of the housing. Radial displacement of the housing ends reduces these hoop forces permitting the tubes to start to unroll and the tubes are fully extended over the housing ends and onto and over a portion of the cables.Type: GrantFiled: December 9, 1985Date of Patent: August 4, 1987Assignee: Amerace CorporationInventors: Glenn J. Luzzi, Andrew A. Kominiak
